To all whom it may concerns Be it known that I, ALEXANDERJE. BROWN,

State of Ohio, have invented a new and useful Method of Constructing Masts; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which make a part of this application;

'le the process to be described is equally applicable to masts or stacks of any desired heights and without regard to the particular purposes their erection is to serve, it will be manifest that its greater utility will be in the construction of masts required for observation, signal, or illuminating operations, for

space or wireless telegraphing. These purposes call for extreme heights as compared with what has heretofore been realizable, ex cept by abnormally expensive tower constructions, since the raising of masts to the elevation demanded for the best results has hitherto not been practicable.

It is the object and aim of the present .application to point out a novel or simple mode of building up this kind of structures, and

shop work, With the attending advantage of hydraulic riveting and a complete inspection of the Work as it progresses.

For the purpose of illustration in the course of the explanation I am now about to make I have shown and described an insu Wireless telegraphy. As above stated, however, my method of forming the mast proper sense intended to be limited to the special field of utility indicated by the drawings.

In the drawings, Figure 1 is a plan view, in

guys connected to the same and to their several' anchorages, as indicated. Fig. 2 is a diagrammatic elevation of the'same, showing both permanent and temporary guys, but withthe front and rear guys removed. Fig. 3 is a segment or section employed in my mode of constructing a mast in elevation, with the ladder preferably fixed interiorly of the same, denoted in dotted lines. Fig.

segments of said m'ast at the point 0 4 is a plan view of the segment shown in Fig.

Fig. 5 is an upright sectional view of a i portion of a mast constructed according to my method through the plane of the juncture connection of any t'w 0 segments thereof.

Fig. 6 is a plan view of a portion of aclg'acent their juncture. Fig. 7 represents the lower part of a mast constructed under and by my pres ent method, displaying six segments or sec tions thereof as they figure in such construction. Fig. 8 is a view, on an enlarged scale, of one of the segments req aired by said method,

with fragmentary views of the sections in place next above and below the same and the provision for lntroducing within and connecting the temporarv supporting-guys to said segments duly disclosed. B 1g. 9 represents a p ortion of a mast of the kind above referreitl to and the extremities of permanent guys attached to the same, as well as repair-balconies that may be usefully provided immediately below the same, and the temporary guys duly indicated that would probably be attached. to the samein the event that the connections of the permanent guys represented as immediately overhead at any time required alterations or repairs from such balconies and for that reason were to be temporarily detached. Fig. 10 is an enlarged view of a form of con-- nection of the permanent guys to the mast I produce. Fig. 11 indicates the uppermost part of a stack or mast in the course of erec- I tion under my process with the form. of crane I employ in position for lowering given segment into place. Fig. 12 indicates a like View when the crane having put a gi en. segment in place, as shown in Fig. i l, is 2:" posi- 1:

tion to e raised to the next stage of the Work. Fig.13isa planviemwithall tube parts (hereinafter described) omitted. til i:- from, of a form of supportingbracket that may be employed With advantage in my method for the upright or vertical form of crane I use. Fig. 14 is a side view of thy bracket with portions of the tulmlar-c mneetion features indicated which in one form or another are used. Fig. 15 is a side View of the parts shown. in F ig. 13, but with the toning-bolt, that is projected. in said. ligui thrust backwarclly (as signified by dottedline) within a housing provided fOT-tiln pu1' pose; and Fig. 16 is a sectional view on the lines X X of Fig 14.

In. theseverai figures the same parts are denoted by the same referential letters.

M is the mast proper in place, and G G G G permanent guys for the same and g, g, g

g and 9" those used for temporary supporting purposes atthe various stages of the erection. The ai'iehorages A A for these guys as laid out in the drawings are arranged around the site of the mast in twos at the several quadrant-points in radial relation to each other. They may be constructed in any manner deemed best'suited to their functions.

F indicates a iran're for the transmittingwires employed, which may also take any form that is-considered best adapted to its "or crane-holes It for the reception at the same purpose.

B B are repair-balconies for the guy con nections, and as such are of course severally located at various points on the mast M imn'iediately beneath the permanent guys G G G G", &c. Said guys themselves in the drawings herewith are made of a series of lengths of steel cable insulatively linked together and connected at one end of the series 'to the mast and at the other end to their several anchors. While any appropriate form. of insulated, connection is open for use, in the illustrations of the particular kind of mast time of the bolts 6 oi the double brackets d and the handle H of the worm-gear arrangement w, which is provided for revolving the crane as hereinafter explained. At points where the mast'M is to be temporarily guyed "during its construction the several segments S-shouldbe provided with other apertures or "holes'h, equidistantly spaced around the same, for the reception of the extremities of said guys and in such relation with respect to theapertures or crane-holeslz as will leave an openpassage-way between the guys for the upward hoist otthe segnents to their several placements. Bearing-blocks may be usefully laid behind said guy-holes, as is indicated in dotted lines and by e.

D is a form of double bracket 1 provide to serve as a sort ofsocket-support for the cranes standard during the process of assembling the several segments S into the mast M. vlt is provided with a base or support 1, with legs or contact-bearings I, that conform to the outer circumferential configuration of the segments themselves. said brackets project outwardly from said base into a sleeve bearing m of suitable dimensions to receive afixed tubular connection n within the same. The upper and lower members of the bracket D are denoted by (1. They each contain longitudinal recesses that serve as house-tugs for a sliding bolt 1), which bolt is threaded at its inneror projective end to receive ahand-nut f. The sliding bolts 6 are provided with heads 6, whereby their reciprocal movements outwardly of theirhousings will be stopped when such heads bring up against the guide pieces or stops t in said housings provided for the purpose. These guide-pieces are located at such points in their respective housings as will limit the outward reciprocatioir'of the bolts I) and enable the bracket parts (1 to-be brought firmly into bearing against the segments S when the hand-nuts f are screwed home against the washers v.

C is a crane. It is composed of a fixed frame lr, carrying sheaves s s, and a tubular post or standard 1, which latter is so related to the frame It and the sheaves s 8, carried thereby, that its here will always be in vertical alinement with the bore of said sheaves. t is a hoisting-rope reeved aroundsaidsheaves and having the strands thereof that are to be connected with the source of power passing downwardly from the sheave 8' into and through the bore of the post or standard 7*. The hoisting end of said rope is shown as carrying a bail b, the forks of which-are spread to span the annular connecting-block N and to be bolted or otherwise attached thereto when said blocks are in place within their respective segments, as hereinafter explained.

To the inner endof the frame It is attached a chain-hoist p in operative connection with a guiding-beam.'Ofor the purpose of raising and lowering the same. This guiding-bean1 at one end embraces the post r of the crane (J as a sliding sleeve or collar and extends horizontally therefrom to a suitable distance to overlap the top of the mast M at each stage of its construction when revolved about the same, and. the crane C is in the described place for such movement. The under side of the beam 0 carries a hoisting-tackle J, adapted to hook on and raise the double bracket D. Said beam is otherwise provided with bolts at suitable points to enable it to thereby become bolted across the top of a segment S through the bolt-holes of the annular conneeting-blocks N. The blocks N and N are annular steel castings of proper dimensions to it into the segments S S at their ends. They have interior flanges around each: edge, duly provided with bolt-holes throughout their extent. Said blocks are firmly riveted in their respective places within the segments. S. As shown in Fig. 5, I have made the block N, which is to occupy the lower end of a given segment when raised to its place in the mast.

with a downwardly extending centering flange at around its lower edge.

H re resents rod-bolts passing through the bloc (s N N of contiguous segments, and thereby locking them in place.

w indicates a worm-gear arrangement for revolving the tubular post 1' through the handwheel w.

Having ex lained the several parts employed in sai method, the operation itself b which they are utilized is substantially as fo lows, namely: The se ments S, having been made in the shop wit the blocks N and .-\N duly riveted into the same, as .pointed out, the three se ments S are bolted together at the site of the mast and raised into place. Temporary guys may now be added (and from time to time thereafter as the work progresses) by passing the mast ends of such guys through the guy-holes h and over the bearing-block 1) down to rod-bolts H in the connecting-blocks N, where the same may be secured very conveniently to the bolts themselves by, for instance, removing a top nut in each case and substituting therefora speciallyprepared clevis-nut,with which the guy-rope may be connected. The crane C is next attached in its upright operative position by bolting the bracket members (i of the double bracket D (carrying the crane) through the crane-holes h of the adjacent segments S. A fourth segment may now be brought u by means of said crane, and when its loa has been hoisted above the level or plane of its place said crane is revolved one hundred and eighty degrees by means of the worm-gear arrangement to until the segment is above said place, when the latter is immediately lowered into position and secured to the stack by the rod-bolts H. volved to its former position, which will bring the beam 0 above the segment just placed and in position to be bolted to the same through the bolt-holes in the connectingblock N. Under these conditions the bolts 1) of the bracket parts cl can be unloosed and the double bracket D hoisted by the tackle J until said bolts are in front, respectively, of the crane-holes h in the fourth and fifth segments, to which the bracket D is attached, as before. The crane C by this operation is of course carried upwardly a corresponding distance and in position to elevate a sixth segment to its place as soon as the beam 0 is loosened and raised by the chain-hoist 7). The

The crane is thereupon reoperation just described is of course to be repeated until each segment required for the masts construction has been thereby brought to and secured in its proper place in'the series.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is'- 1. The process of constructing masts of sheet metal or similar material, by first forming the material into cylindrical segments, with holes for crane-bolts therein, and annular connecting-blocks at each end, and, thereafter, successively superimposing such segments, one upon another, to constitute the mast, by hoisting them by means of a crane which is bolted to the work in progress, in operative position to deliver, a segment above the same, and, which, after the de ivering and permanent fixing of a given segment in place, is itself raised to a osition for delivering the next segment, by a guiding-beam to said work, to sustain the crane during the operation, and, then, unbolting the crane from said work; and causing power to be applied to a hoisting apparatus connecting the beam and crane, untllthe latter is brought to the new position where it is secured as before.

2. The process of constructin masts of sheet metal, or similar materia, by first, forming the material into cylindrical segments, with holes therein, suitably spaced, for temporary guy-ropes, and ,holes for cranebolts, and, also, annular connecting-blocks riveted, within the same at each end, and, thereafter, successively superimposing such segments, one upon another, to constitute the mast, by hoisting them by means of a crane which is bolted to the work, in progress, in operative position to deliverits load above the same, and which is, itself, raised to new positions for operation, by first temporarily fastening a guiding-beam, provided for the purpose, across the top of said work, to sustain said crane, whilebeing so raised, and, then, unbolting the same from the work, and causing power to be applied to a-hoisting apparatus connecting the beam and crane, until the latter is brought to the new position where it is secured as before.
